>>César, with version 2.88 behaves the same previous version. Following my code. This piece of code is inside SCAN, because I am generating several XLS files. To work fine I have to omit parameter "xlExcel9795" on the line loExcel.ActiveWorkbook.SaveAs(m.nmPlanilha+'.XLS', xlExcel9795).

César,
Note that in my code I am not using REPORT PREVIEW, but as you asked, I changed my code to see the version, and the version is v2.88a ALPHA 2011.12.06
